It is a superhard substance that is inherently lubricious and resistant to wear and is an atomic crystal; it is resistant to oxidation at high temperatures. Moreover, it can resist cold and hot shock, and is heated to above 1000 ° C in the air, and is rapidly cooled and then heated rapidly without breaking. It is precisely because of the excellent properties of Silicon Nitride Ceramics that it is often used to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds. If a silicon nitride ceramic that is resistant to high temperatures and does not easily transfer heat is used to manufacture the heating surface of the engine component, not only the quality of the diesel engine can be improved, fuel is saved, but also thermal efficiency can be improved.
